When Disney announced its Infinity platform for combining toys and video games in a single entertainment platform, it was easy to dismiss it as a Skylanders copycat. Activision has seen more than $1 billion in revenues from its Skylanders toy-game hybrid products. Disney’s offering is similar, but it is pouring a lot of its game- and toy-design chops into making sure that Infinity will be unique and valuable, considering that fans could pour a lot of money into this new platform over time.
